I am wondering if anyone else has had this problem. I have a sudden loss of power to the ECM, the observation is no check light, and the fuel gauge pinned on full. I going to take care of the obvious things today and get rid of the fusible links and switch to maxi fuse block. The common sense thing to check is the loss of the fuel sender and back pedal to the battery. I am afraid fixing the fusible links may not fix my problem as it is running now and I am wondering if anyone had the same problem and knows what the proper fix is.
Well, I once had an electrical problem with a short in the dash behind the instrument cluster on a Chevy work truck that scared thee Crap out of me with a huge puff of smoke. Drove fine, kept right on going, lost half the instruments at least!
White Knuckle drive, straight to Escondido Auto Electric. Short in the Cluster. The guys were laughing when I came in.
Smelled like the 4th of July...
A real ClusterShort for sure.
I'll look in my 1990 FSM book sitting right here, as I have the zaxt same drivetrain as you, see if it says anything. I do suspect, hopefully, just a short.
Are those the only 2 symptoms?
